whaaaaaa, what is this ? ...interesting stuff. Its kinda voxatron inverted seems a little clumsy, but give em time to perfect it. The other projects are cool too! Lots of interface ideas.

It would be impossible to play Voxatron on that, no matter how much time you give them to perfect it. Unless hologram technology gets here sooner than I think, it would be impossible to make the gaps that happen to be sandwiched between two voxels along the z-axis in mid-air. Other than that, though, it seems pretty nifty!
